In Memoriam: Gregory Long

With a heavy heart, we share the recent passing of our wonderful, kind colleague, Greg Long.

Greg Long

Greg Long had an amazing, joyful spirit and energy and a shared devotion to creating sustainable design.  With a ready smile, he was always generous about sharing information and project experience. Greg touched so many people through the establishment of his design/build/maintain business, Capitol Greenroofs and its Group Site, an excellent discussion group forum.

“On April 28th, 2018 Greg Long passed due to complications of treatment for advanced cancer.  Many in the Washington, DC area knew him as a long term greenroof/greenwall promoter, designer, installer and owner of Capitol Greenroofs.

Greg grew up in Northern PA and went to Penn State University for a BA in Landscape Architecture.  After college he worked in the DC area at several engineering and architectural firms before catching the Greenroof bug and starting to promote these to anyone who would listen.  For 12 years he was a member of Green Roofs for Healthy Cities (GRHC) and was a certified Green Roof Professional (GRP).

Aside from work, he was an avid outdoorsman who liked to fish, camp, hike, snowboard, and float down river in any way possible.  Making friends whether at work or play was very important to him and he will be missed by many.” ~ Bob Long

Here are a couple of photos I took of previous CitiesAlive conferences:

Greg certainly will be missed by many within the Washington Metro Area, throughout North America, and beyond.  His high quality body of greenroof work will stand as a testament to his passion for living architecture.  Just some of his many projects include the American Psychological Association (APA) HeadquartersVirginia Commonwealth University (VCU) Pollak BuildingAmerican Psychological Association (APA)/ World Resources Institute (WRI) HQCity of Charlottesville City Hall/Police StationU.S. Tax Court, and the Herrity Building Parking Garage Demonstration Garden.

In Greg Long’s memory, we are featuring one of his outstanding works from 2014, the American Psychological Association (APA) Headquarters, as our current Project of the Week.

“Even the northeaster that blew through with some driving snow showers couldn’t keep us from meeting our deadline. Not ideal to work but hey….sometimes you just have to deal with what mother nature throws at you.” ~ Greg Long, Capitol Greenroofs, 2014

Greg didn’t search out the spotlight, and so I don’t have any more photos at the moment to share.  We would like to invite everyone interested to add your comments and send condolences below to Greg’s father, Robert (Bob) Long of Carolina Stonecrops.  Please  send photos to and I’ll add them to this post.

Greg will be sorely missed by and family and friends, and all of us within the greenroof community send our heartfelt condolences to his dad, Bob Long, and Greg’s loved ones.

Greg, may you rest in peace.
